FXP(4) FreeBSD Kernel Interfaces Manual FXP(4)
NAMEfxp -- Intel EtherExpress PRO/100 Ethernet device driver
SYNOPSIS
To compile this driver into the kernel, place the following lines in your
kernel configuration file:
devicemiibusdevicefxp
Alternatively, to load the driver as a module at boot time, place the
following line in loader.conf(5):
if_fxp_load="YES"
DESCRIPTION
The fxp driver provides support for Ethernet adapters based on the Intel
i82557, i82558, i82559, i82550, and i82562 chips.
The fxp driver supports the following media types:
autoselect Enable autoselection of the media type and options
10baseT/UTP Set 10Mbps operation
100baseTX Set 100Mbps (Fast Ethernet) operation
The fxp driver supports the following media options:
full-duplex Set full duplex operation
Note that 100baseTX media type is not available on the Pro/10. For fur-
ther information on configuring this device, see ifconfig(8).
The fxp driver supports reception and transmission of extended frames for
vlan(4). This capability of fxp can be controlled by means of the
vlanmtu parameter to ifconfig(8).
The fxp driver also supports a special link option:
link0 Some chip revisions have loadable microcode which can be used to
reduce the interrupt load on the host cpu. Not all boards have
microcode support. Setting the link0 flag with ifconfig(8) will
download the microcode to the chip if it is available.
HARDWARE
Adapters supported by the fxp driver include:
+o Intel EtherExpress PRO/10

+o Intel PRO/100B / EtherExpressPRO/100 B PCI Adapter
+o Intel PRO/100+ Management Adapter
+o Intel PRO/100 VE Desktop Adapter
+o Intel PRO/100 M Desktop Adapter
+o Intel PRO/100 S Desktop, Server and Dual-Port Server Adapters
+o Contec C-NET(PI)-100TX (PC-98)
+o NEC PC-9821Ra20, Rv20, Xv13, Xv20 internal 100Base-TX (PC-98)
+o NEC PC-9821X-B06 (PC-98)
+o Many on-board network interfaces on Intel motherboards
DIAGNOSTICSfxp%d:couldn'tmapmemory A fatal initialization error has occurred.
fxp%d:couldn'tmapinterrupt A fatal initialization error has occurred.
fxp%d:Failedtomallocmemory There are not enough mbuf's available for
allocation.
fxp%d:devicetimeout The device has stopped responding to the network,
or there is a problem with the network connection (cable).
fxp%d:Ethernetaddressff:ff:ff:ff:ff:ff In some Alpha's (AXPpci and
Multia) you must tell the driver to use (slower) I/O rather than memory
to access the card. Create, if it does not yet exist, and add to the
file /boot/device.hints the line ``hint.fxp.0.prefer_iomap="0"''.
fxp%d:Microcodeloaded,int_delay:%dusecbundle_max:%d The chip has
successfully downloaded the microcode, and changed the parameterized val-
ues to the given settings.

The fxp device driver first appeared in FreeBSD 2.1.
AUTHORS
The fxp device driver was written by David Greenman. It has then been
updated to use the busdma API and made endian-clean by Maxime Henrion.
